I’ve said it many times and I’ll repeat it here - Debian will be one of the few Linux distros we have right now, that will still exist 100 years from now.
Yea, it’s not as modern in terms of versioning and risk compared to the likes of Arch, but that’s also a feature!
It'd certainly be nice, but if you've ever seen an organisation unravel it can happen with startling speed. I think the naive estimate is if you pick something at random it is half-way through its lifespan; so there isn't much call yet to say Debian will make it to 100.
This doesn't strike me as a strong argument. That naive estimate (in whatever form[0]) is typically based on not knowing anything else about the process you're looking at. We have lots of information about Debian and similar projects, and you can update your estimate (in a Bayesian fashion) when you know this. Given that Ian Murdock started Debian 31 years ago I think more than 100 years is a very reasonable guess.

In a way, Flatpak/Snap/Docker was mitigations to support old programs on new systems, and old systems with updated software no longer compatible with the OS. Not an ideal solution, but a necessary one if folks also wanted to address the win/exe dominant long-term supported program versions.
If working with unpopular oddball stuff one notices the packages cycle out of the repositories rather regularly. =3
The Lindy effect says nothing about popularity, which is how I translate your use of 'dethrone' here. It observes that something's duration of existence correlates with its chances for existence in the future.
Yet, it's lasted 31 years, which is a pretty insane amount of time in tech. This on top of being kept up to date, good structure, really good contributions and advancements.
On the other hand, you look at centos, redhat, and oracle and their debacle. How much did they fragment that area.
And then we have Debian just chugging along.
